There's a few different actions. First, since it isn't developed the paper effectively acts extremely slowly. Whereas normal photographic paper would be around 6 or up to 20 ISO, doing it this way is almost immeasurably slow. Getting similar results without a pinhole and just something layed on top (photogenic drawing), it would take several hours in direct sun to get a decent image. The next contributing factor is that some papers "print out" easier than others. The hard ones will take hours in direct sunlight, while the easier ones might take "only" 30 minutes or so. The final factor is that pinhole is a very slow and low contrast method of exposure. Silver halide paper suffers from "repricocity failure" where basically during a very long exposure, the material becomes massively less sensitive. This is why film is so hard for astrophotography. A 100 ISO film over several hours can become something more like 1 ISO. Either way, the end result is that the paper gets very slow and gains a very wide exposure latitude, nearly impossible to over expose.

I have a friend who did that for a few months and it took her iirc 2 years to get over the gum fixation.. even without nicotine, she always had to have some gum for cravings

I think she was chewing the nicotine gum a few times a day, but I'd still be careful about it.. iirc the reason she did it was she wanted gum and the only gum her parents had regularly was nicotine gum and she was like 14 at the time

I think the key with vaping (not necessarily with Juul though due to market availability) is that it's very easy to decrease the dosage of nicotine without reducing the fixation amount. For traditional cigarette smoking you want a high amount of nicotine to fill that void (and also to get through the other side of other addictive substances in tobacco beyond nicotine) and to effectively "get hooked" on vaping instead, to the point that normal cigarettes are completely unattractive to you.. Afterwards, decreasing dosage with a vape is super easy, especially if done in a blind way, ie, buying two identical flavors at different dosages (your "normal" and the lower dose) and put them into two carts. Pick a random one each day to use. I've heard of people doing this all the way down to 3mg to get over the lowest dosage hump even. One has no nicotine, the other only has 3mg. Eventually the non-social fixation (ie, at your house alone) stops, and the social fixation (ie, outside of a bar, etc) is controllable with no nicotine... Then that's not even getting into the different ohm ratings etc that further control dosage without affecting the fixation of using the vape.

edit: note I say "easy", but its not a short process.. If you try to go immediately from 48mg to 3mg you won't have a good time. It takes months for each step down

Am I the only person who can never have "full brainpower" anytime within 3 hours of waking up?

Honestly, they go to bed at the time the parent sets a routine after probably 3 or 4yo. My kids consistently go to bed at 9pm for school, 10pm on weekends/summer, and typically no problems going to sleep or waking up in the morning. It's been like that for years now. The time they did have trouble going to sleep at the right time is when they visited grandma for 2 weeks and had a wild and inconsistent sleep schedule the entire time. It took them about 2 weeks to adjust back to the normal routine. One hour adjustment from weekends etc is easy, but 2-3 hour adjustment is a huge stumbling block

It blows my mind some of the comments here of people who do this. I can literally not recall a time that mornings were not miserable.. and that includes when I am jet lagged (either going to a country, or coming back) and naturally fall asleep by 9pm and awake by 5am. Mornings are boring and I can never really get into enjoying them. The most fun I've had was one time in China I woke up at 4am and went to photograph things at 430am.. But that's not something I'd do every day, and even at the time I felt kinda cranky about it.

I have 2 kids, so have to have some structure to my sleep schedule. Left to my own devices, my natural bed time is 3-4am and I'm awake at 11am-12pm. With kids during school (in summer they sleep in too) it's a bit more reasonable though probably less healthy. Asleep by 1 or 2am and wake up at 8am. They're 9yo and 6yo and the oldest is responsible for getting the younger up if she doesn't wake up with the alarm. They're both 90% ready by the time I wake up (they prefer to wake up at 7am or even 6:30am to have some play and tv time before school). This includes getting themselves dressed, hair and teeth, and the picky youngest packing her own lunch. Their school starts at 8:45am and I'm typically out the door at 8:30am and back by 9am.

I don't really start working until 10am most days, but I'll do some passive stuff like read emails and industry news type stuff while having coffee. At 10am I'm getting started, at 11am on a good day I'm hitting a stride. Typically not doing my best coding work until at least 2pm though after lunch. Depending on how in the zone I am and what I'm doing, I work until 5:30pm to 7pm. I have the benefit of being remote and setting my own hours though, so it's definitely a blessing I know many people aren't fortunate to have. Have dinner with the family after I stop working, and then just relax with dumb activities (TV, social media) and of course bonding stuff with family, until the kids go to bed at 9pm. When they go to sleep I sometimes work for a couple more hours (coordinating with 12 hour different timezone is fun), but more usually relax with peace and quiet playing games, messing around with interesting research (both hobbies and work), or just dumbly watching TV, or do some hobbies (analog photography/darkroom printing)

I sacrifice sleep more than I should, and typically will have a 10 minute power nap after I'm done working.. But honestly, as long as I'm getting 6-7 hours of sleep, I feel just as well as when I'm getting 8 or 9. When I get less than 6 though I definitely regret it the next day. And I don't mean just sleeping in on weekends. I had about 2 weeks this summer where I had no kids, no wife, and basically nothing guiding my sleep schedule. I'd tried naturally sleeping for a week with no alarm and realized I felt more tired and it was consuming a lot of time. I was waking up at 11 or 12. So I started setting my alarm to a more reasonable 10am and was in bed by 3 or 4am, and always felt well rested after I got out of bed.

Some people can not "relax" and enjoy mornings. My goal with mornings is to get that phase of day over with so I can work and then get to a free evening. When I'm jetlagged it's pretty interesting becoming a forced morning person, but it's always proven to me that having 3 hours of free time in the evening is so much more valuable to me than 3 hours of free time in the morning.

Really cool, see a few missing film types (Superia 800 and 1600, Cinestill 800T/Vision3 500T) would also be really interesting if there was listings for cross-processing, especially of slide film in C-41. Each stock has its own set of casts and color crossing and it can be pretty difficult to figure out what that is for each film stock.

Also completely unknown how you'd do it, but giving any kind of data for pushing the B/W films would be really interesting too

There was no disclosure that they were hemorrhaging money nor that their product was significantly unprofitable though. I imagine interest would've been a lot less had that fact been public at the time. They were literally selling it as "invest now and we all make a lot of money later"

I think the SEC is interested in the conditions around their ICO, the misleading tactics, and the aftermath of it, more than the fact that they did an ICO

Along that same line, Fear and Loathing in Las Vegas is a pretty good movie at warning that playing it fast and loose with recreational drugs beyond alcohol can have you end up with a very bad time

> I think writing an OS from scratch is discouraging and not very accessible because... writing an OS is discouraging and not very accessible

I actually learned C by writing an OS from ages 16 to 18. I don't know if I'd recommend it to everyone, but it is surprisingly accessible if you limit scope. The real hard parts are dealing with complicated hardware. If you care about the basics like keyboard, mouse, display, flat memory, no threads, then its incredibly easy in 16bit C for x86. 32bit C (i386) is also easy, but does require a bit more setup etc.

It is incredibly educational learning how to write your own libc and having to manage toolchains etc. You very quickly learn the exact boundaries of what is computer controlled and what is toolchain controlled, and of course what is controlled by your own code.

And yes, I had a similar experience to you re: emulators. Tried making a simple 8086 computer emulator. CPU instructions are really easy and really the part I enjoyed. Emulating the hardware and all the machine protocols gets very difficult and complicated very quickly. I ended up, after a few months of that, rescoping the project to only be an 8086 CPU emulator, which was one of the few projects of my youth I actually completed.

I would think the real test is to do some pulling on the cable to make sure it's reasonably sound structurally, and also maintaining 10 GBit at the spec maximum for cat-6... but really if it works for however long you run it, what does it matter

The credit is currently wrong, it should belong to one of the developers on my team, David Jaenson.

My comment was an early disclosure before I fully understood how sensitive the details were. Even without going into detail or providing any code it was very irresponsible of me to off hand just mention that possibility. It didn't click how sensitive things were until a bitcoin core dev confirmed it. Sorry anyone who sees this. I merely reported the exploit, David Jaenson is our genius security researcher that definitely should deserve all credit.

Actually it only seems to be a side effect of our test environment. Using a more realistic environment makes it not effective, sorry for the false alarm
